Can you combine two existing stations in openTTD?

I recently started a new openTTD game, and forgot to hit ctrl while putting down my first airport near a bus station. I want the passenger service of both to merge together, but I'd rather not write off the airport's cost as a loss.

Is this possible?

Solution 1:

No, you cannot merge two stations after they are built. You can however rebuild one of them and then join them back in with the other station.

Solution 2:

As a possible workaround, you could build a second bus station linked to the airport and provide a bus service that transfers passengers from the first bus station to the airport. That's what I'd do, anyway.
